gem-Difluorination of carbon–carbon triple bonds was conducted using Brønsted acids, such as Tf2NH and TfOH, combined with Bu4NBF4 as the fluorine source. The electrochemical oxidation of a Bu4NBF4/CH2Cl2 solution containing alkyne substrates coul

We show that a catalytic amount of electro-generated acid (EGA) prepared from the oxidation of a Bu4NB(C6F5)4/CH2Cl2 solution catalyzes effectively the tandem cyclization of epoxyolefins, producing the corresponding polycyclized compounds in 23%–57
